This cartridge only works with Flint & Walling booster pumps in the PB series and matches Grainger part numbers 22W736, 22W737, 4YC11 and 4YC12. It will not fit other pump brands, different series or models outside the listed part numbers.

14-Stage Capacity

Fourteen stages deliver the pressure rise designed for the original PB1014S101 and PB1014S103 pumps. Systems requiring fewer or more stages need a different cartridge, and this unit cannot be reconfigured to change its stage count.

Questions about this item

Which booster cartridge version fits my PB1014S101 or PB1014S103 pump?

This cartridge is compatible with Flint & Walling PB1014S101 and PB1014S103 models and matches Grainger part numbers 22W736, 22W737, 4YC11 and 4YC12.

What does the 14-stage rating mean for pressure output?

Fourteen stages multiply pressure across each impeller, delivering higher head than fewer-stage cartridges for the same flow range.

How does the SS construction and included coupling affect installation?

Stainless steel resists corrosion and the supplied coupling, shaft, discharge bearing, stage components and two O-rings let you rebuild the cartridge without extra parts.
